>>雜誌用正片, 係因為製作流程, 唔係因為比負片好. >>製作流程是一點:但真正原因是正片能放大很多,也不會太粗劣方便裁放.....
曾經問過印刷人,唔知我有無理解錯。分享一下,有錯請更正:
流程應是使用掃瞄器,把圖像轉化成為數據。圖像可以是正片(膠片)、相片、反射搞(紙張)。當然,亦可以直接使用數碼相機。
使用正片原因: 因為正片的密度最高達3.5,而一般相片只是2.5;在掃瞄複製時,光暗位、反差、層次會有分別.... 另外,正片能較穩定記錄被攝物的顏色,而負片實在有太多變項.... |

Personal thinking, digital photography introduces some "troubles" on post-processing, e.g., time and techniques to make decent pictures.
Of course, films have their "troubles" too, but both ends will have their advantages. Hence, I take film and digital photography without sacrifice one of them until there is no film available on the market.

看來現階段還是正片最好質量!但還是那一句:幻片升級之選,數碼最合識< 入門及提升技術而且方便 >SLR還是要小心選擇為準..... |

我現時用 300D. 目的只為磨練技術, 希望日後轉用 SLR 能百發百中o
何解? Digital 的色彩局限於 0 同 1 之間, 而 film 理論上是無限o

岩岩岩 其實好多人最後都係由數碼玩返菲林 |

My experience is the same as Superman... Coz we started from film...not start recent years from DC...
用數碼,一樣可以用非林機拍SLIDE,有什麼相干了 |
